Oh man, you just aren't listening... WE DON'T KNOW, YOU DON'T KNOW, NONE OF US KNOW!
Apple has not said anything about the music you upload. They said "Nor will it be offered in iTunes Match" in what you sent - which to me conclusively refers to only
this. While I EXPECT you are right, I hope not, and will not really know until next week. Saying something "tends" to be part of something else flys in the face of something being explicitly mentioned as part of Apple Music, which my image illustrates it is part of.
Google used to offer lossless uploads of your music with Google Music (now RIP). The image I sent you was from the features page of Apple Music, NOT the feature page of iTunes Match. I FULLY understand the distinction, I fully understand what you are TRYING to say, but there is zero zilch nothing conclusive saying your iCloud Music Library part of Apple Music will not be getting lossless uploads, and unless you can point me to Apple saying that, I will still hold hope for my recorded music.
